So I've been researching replacement Cranksets for my beat up 1999 Giant Xtc. I saw this really nice Bontrager King Earl Mountain Triple Crankset for a really nice price, but it says "Tru-Vativ Howitzer bottom bracket interface durability" Does that mean it can only use that BB? or is it standard ISIS? I'm confused. Also will I need to buy crankbolts? I'm debating this because I am a hefty boy at 5'10 220 lbs =( Thanks for any information.
